RELATIVE ABUNDANCE 



Distinctive differences in mean annual density of larvae were 

 evident between the Gulf of Maine-Cape Cod Bay region and 

 southern New England (Buzzards Bay-Block Island Sound). 



Consistently higher densities were recorded in southern New 

 England (Table 2). Reduced density within the Cape Cod 

 Bay-Gulf of Maine complex may reflect the influence of pre- 

 vailing southwesterly winds during the period of larval oc- 

 currence. Prevailing winds during summer are onshore in
